Cooler Master Silencio 550
ATX Tower Case
Street Price

Being one of the largest PC case makers, Cooler Master has a seemingly endless selection ranging from relatively small budget models to enormous EATX server towers and offerings of every size and price in-between. Like most manufacturers they've largely ignored the notion of the silent or quiet case. To our recollection, their only serious attempt at such a chassis was the Sileo 500 which we reviewed in 2009. The Silencio 550 appears to be an updated version for 2011.

The box.

The case.

Like most cases currently marketed as quiet, the Silencio takes the form of a simple but sleek tower with a front door, solid panels and controlled ventilation to limit the amount of noise from escaping. The case has a black matte finish, a glossy reflective front door and stands a modest 18" tall. It bears a close resemblance to the NZXT H2 but has a more streamlined appearance, lacking the fan placement and hard drive dock and covers at the top of the case. It also has a bit intake ventilation with slits running up halfway up the sides of the front bezel.


The case ships with instructions, screws, drive rails, a PC speaker, a set of thin plastic ties, and rubber damping pads for the power supply and two case fans, even though only one extra fan can be added.
